impurities, particularly iron and transition metals, absorb light at specific wavelengths in the UV and visible range. A quartz window produced from powder with elevated iron content will show absorption bands that reduce transmittance and alter the spectral profile of the illumination system. For photolithography applications operating at 193nm or below, even trace-level absorption in the optical path can affect exposure uniformity and ultimately CD control on the wafer.<\/p>\n<p>\u30d2\u30c9\u30ed\u30ad\u30b7\u30eb\u542b\u91cf\u306f\u3001\u69cb\u9020\u7528\u9014\u3068\u306f\u7570\u306a\u308b\u65b9\u6cd5\u3067\u5149\u5b66\u90e8\u54c1\u306b\u3068\u3063\u3066\u3082\u91cd\u8981\u3067\u3059\u3002\u3044\u304f\u3064\u304b\u306eUV\u5149\u5b66\u7528\u9014\u3067\u306f\u3001\u5358\u306b\u6700\u5c0f\u5316\u3059\u308b\u306e\u3067\u306f\u306a\u304f\u3001\u7279\u5b9a\u306eOH\u542b\u91cf\u7bc4\u56f2\u304c\u76ee\u6a19\u3068\u3055\u308c\u307e\u3059\u3002\u306a\u305c\u306a\u3089\u3001OH\u306f\u3001\u30b7\u30b9\u30c6\u30e0\u306e\u5149\u5b66\u8a2d\u8a08\u306b\u5408\u308f\u305b\u308b\u5fc5\u8981\u304c\u3042\u308b\u65b9\u6cd5\u3067\u3001\u6eb6\u878d\u30b7\u30ea\u30ab\u306e\u5c48\u6298\u7387\u3068UV\u900f\u904e\u7387\u306e\u4e21\u65b9\u306b\u5f71\u97ff\u3092\u4e0e\u3048\u308b\u304b\u3089\u3067\u3059\u3002<\/p>\n<hr>\n<h2><span class=\"ez-toc-section\" id=\"Grade_Requirements_for_High_Purity_Quartz_Powder_for_Semiconductor_Applications\"><\/span>\u534a\u5c0e\u4f53\u7528\u9014\u306e\u9ad8\u7d14\u5ea6\u77f3\u82f1\u7c89\u672b\u306e\u30b0\u30ec\u30fc\u30c9\u8981\u4ef6<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<style>\n.gindtay-table-wrap{width:100%;overflow-x:auto;margin:1.5em 0;}\n.gindtay-table{width:100%;border-collapse:collapse;font-size:13px;font-family:-apple-system,BlinkMacSystemFont,\"Segoe UI\",Roboto,sans-serif;}\n.gindtay-table thead tr{background:#0d2a45;color:#fff;}\n.gindtay-table thead th{padding:12px 14px;text-align:left;font-weight:600;font-size:12px;letter-spacing:0.03em;white-space:nowrap;border:none;}\n.gindtay-table thead th:first-child{border-radius:6px 0 0 0;}\n.gindtay-table thead th:last-child{border-radius:0 6px 0 0;}\n.gindtay-table tbody tr{border-bottom:1px solid #e8ecf0;transition:background 0.15s;}\n.gindtay-table tbody tr:hover{background:#f0f7ff;}\n.gindtay-table tbody tr:last-child{border-bottom:none;}\n.gindtay-table tbody td{padding:11px 14px;color:#334155;vertical-align:middle;line-height:1.4;}\n.gindtay-table tbody td:first-child{font-weight:500;color:#0d2a45;}\n.gindtay-table .grade-pill{display:inline-block;padding:2px 8px;border-radius:20px;font-size:11px;font-weight:600;white-space:nowrap;}\n.gindtay-table .g-4n{background:#e8ecf0;color:#475569;}\n.gindtay-table .g-5n{background:#dbeafe;color:#1e40af;}\n.gindtay-table .g-5n5{background:#dcfce7;color:#166534;}\n.gindtay-table .g-5n5p{background:#fef9c3;color:#854d0e;}\n.gindtay-table .g-5n7{background:#fce7f3;color:#9d174d;}\n.gindtay-table .nc{color:#94a3b8;font-style:italic;font-size:12px;}\n.gindtay-table .highlight-row td{background:#fffbeb;}\n.gindtay-table .critical-row td{background:#fff7f5;}\n<\/style>\n<div class=\"gindtay-table-wrap\">\n<table class=\"gindtay-table\">\n<thead>\n<tr>\n<th style=\"width:22%;\">\u7533\u3057\u8fbc\u307f<\/th>\n<th style=\"width:18%;\">SiO\u2082\u7d14\u5ea6<\/th>\n<th style=\"width:13%;\">Al\uff08ppm\uff09<\/th>\n<th style=\"width:13%;\">Fe\uff08ppm\uff09<\/th>\n<th style=\"width:16%;\">\u30a2\u30eb\u30ab\u30ea (ppm)<\/th>\n<th style=\"width:18%;\">OH\uff08ppm\uff09<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>CZ\u308b\u3064\u307c\u306e\u5916\u5c64<\/td>\n<td><span class=\"grade-pill g-4n\">4N \u00b7 99.99%<\/span><\/td>\n<td>&lt;

risk is higher in semiconductor-grade quartz powder than in most industrial material categories. The number of suppliers globally who can consistently produce verified 5N5+ material with full ICP-MS batch documentation and controlled OH content is small. A supply disruption at your primary source, whether from production issues, logistics problems, or geopolitical factors, cannot be resolved quickly if you do not have a qualified alternative. Qualification timelines of 12 to 18 months mean that the time to develop a qualified second source is before you need one
